What can a pebble tell us about the history of the earth? And, what are the geological tools that can unravel this mystery? On this program, Jan Zalasiewicz discussed the planet in a pebble. Topics: science, geology, pebble, planet, groks Source: Groks Science Radio Show Podcast
A huge potential for our energy needs lies at the bottom of the ocean in the form of methane hydrates. But what happens when the ocean "burps" and large amounts of natural gas are liberated into the atmosphere? On this program, MBARI scientist Charles Paull discusses how these greenhouse gases could be abruptly released. Topics: science, methane hydrate, marine geology Source: Groks Science Radio Show Podcast
Where did the atoms in our bodies come from? How did Jupiter shape the evolution of life on Earth? Why is our moon so weird? And, most importantly, how do you make an apple pie from scratch? On this episode, evolutionary biologist and paleontologist Neil Shubin joins us to discuss his exciting new book, "The Universe Within: Discovering the Common History of Rocks, Planets, and People." Topics: evolution, geology, Neil Shubin, cosmology, astronomy, cosmology, Neil Shubin, paleontology,...
The Gaia Hypothesis suggests that the various lifeforms on earth interact to sustain the habitability of the planet. But, could the opposite be true? Is life on earth self-destructive? On this program, Prof. Peter Ward discussed the Medea Hypothesis. Topics: science, medea, gaia, environmentalism, ecology, geology, habitability, mass extinctions, groks Source: Groks Science Radio Show Podcast
Supervolcanic eruptions have the potential to drastically alter the environment and seriously affect human civilization. Understanding the geological consequences of these events continues to challenge scientists. On this program, Dr. John Savino discussed the impact of a supervolcanic eruption.
